This measurement is incremented when an NIDD Downlink Data Delivery Status Notification is sent to the SCS Application Server with a Delivery Status of “FAILURE” for a previously buffered Downlink Data packet. This could happen due to one of the following conditions:

• The Maximum Latency duration for the packet has expired while waiting in the Data Delivery queue.
• A higher priority Data packet replaced the lower priority packet in order to accommodate itself when the Data Delivery queue was full.
• The PDN connection was closed and the PDN Establishment Option was either disabled or set to “INDICATE_ERROR” by the SCS Application Server or OAM configuration.
• The Diameter connectivity to the MME/SGSN was lost.
• A graceful shutdown of the SCEF application was performed.
